Hair clipper



p 1939. o. J. LooPak HAIR CLIPPER Filed June 10, 1937 a, M y f Inventor Patented Sept. 26, 1939 UNITED STATES PATENT OFFICE HAIR. CLIPPER (liner Jennings Looper, Poteau, Okla. Application' June 10, 1937, Serial No. 147,584 I 2 Claims.

This invention relates to" hair clippers, the general object of the invention being to make the blades of substantially semi-circular shape and to so form the teeth that the clipper will make a tapered cut and this form of clipper will eliminate much of the work ordinarily done with the points of shears. Also, by making the blades in an arc of a circle, the axis of which is perpendicular to the plane of movement of the actuating means and at right angles to the length of the handle, the desired portions thereof can be used for cutting the hair and the rest of the cut ting parts will be out of cutting position.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a top plan View with parts in section of my improved clipper.

Figure 2 is a view looking toward the inner side of the outer or stationary blade.

Figure 3 is a similar view of the inner or movable blade.

Figure 4 is a sectional view through the approximate centers of the two blades.

Figure 5 is a sectional view through one end of the two blades.

In this drawing, the letter A indicates the body part of an electric clipper, and the numeral I indicates the outer or stationary blade, while the numeral 2 indicates the inner or movable blade, these blades forming my invention.

As will be seen these blades are shaped in an arc of a circle, the axis of which is perpendicular to the plane of movement of the actuating means with the teeth extending in planes at right angles to the length of the handle or body part A.

The stationary blade I is connected with the head A in any suitable manner and the movable blade is connected to the lever member 3, which is pivoted at 4 and which is connected with the shaft of the motor M by the eccentric means 5, whereby the movable blade 2 is oscillated from the motor. The movable and inner blade has tongue and groove connections, shown generally at 6, with the stationary blade.

The teeth of the movable blade 2 are all of the same length with their forward edges substantially straight and their rear edges beveled downend of the stationary blade.

wardly and rearwardly, as shown at 2'. The end teeth of the stationary blade I are of the same length, as shown at "I, and I find it effective to use .approximately nine of these teeth on each Such teeth are 5 commonly designated as No; 0000. These teeth are approximately of the same length as the teeth of the movable blade 2. The intermediate teeth of the stationary blade I gradually increase in length and cutting depth from these teeth I, to the center teeth, these longer teeth being shown at 8. All the teeth of the stationary blade I are beveled on their outer faces, but only the long teeth 8 are beveled on their inner faces or ends, as shown at 8', and this bevel 8' forms substantially a continuation of the bevel 2 of the center teeth of the movable blade 2, as shown in Figure 4. Of course, the long teeth 8 project beyond the ends of the teeth of the movable blade, as also shown in Figure 4. The long 20 I center tooth is preferably commonly known and designated as No. 1 size.

As will be seen, the inner or movable blade is shorter than the stationary blade, so that during the movement of the blade 2, its ends will not pass beyond the ends of the other blade.

The end teeth of the stationary blade are made Wider than the other teeth, to prevent the same being caught in the scalp. The teeth should be approximately inch wide and should be no deeper than the other teeth.

If desired, the lower rib of the stationary blade may extend entirely under the lower edge of the movable plate to prevent hair from becoming entangled between the two plates or blades. 5

The preferred manner of using this clipper is to push it around the head in a horizontal line, with the fine teeth at the base of the head and the coarse teeth upward. This gives an automatic blend and taper to the hair being cut and eliminates much of the Work ordinarily done with the points of shears.

The object of the graduation in thickness and length of the teeth from the ends to the center is to allow the use of the clipper in either direction around the head. The curvature of the plates or blades permit those portions not being actually used in the cutting operation to be held out of the hair so that it is not necessary to provide slides and the like for covering the blade portion not being used, as is necessary with the straight type of clipper. The barber can select the desired part of the cutting edge in accordance with the cut to be made.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes in the construction, combination and arrangement of the several parts may be made, provided that such changes fall Within the scope of the appended claims.

What I claim is:

1. A clipper device of the class described comprising a stationary blade and a movable blade, a body supporting the blades, means carried by the body for oscillating the movable blade, each blade being of substantially semi-circular shape- With its axis arranged perpendicular to the longi-- tudinal axis of the body, the teeth of the movable blade being of substantially the same sizewhile those of the stationary blade have the end teeth of substantially the same size, with the intermediate teeth of greater length and the long teeth having their inner faces beveled at their ends.

2. A hair clipper comprising an elongated body, a stationary blade of substantially semicircular shape supported from one end of the body, a movable blade of substantially semicircular shape contacting the inner concaved face of the stationary blade, means for oscillating the movable blade, each semi-circular blade having its axis perpendicular to the axis of the body, said movable blade having teeth of substantially the same size, with their ends beveled on their inner faces, the" teeth of the stationary blade being of substantially the same size at the ends, the intermediate teeth being of greater length and gradually increasing in length from the short end teeth to the center teeth, all of the teeth of the stationary blade being beveled on their outer faces and the long teeth of said blade being beveled at their ends on the inner faces.
